Just you set, only once, desired font size for your design. For example if you work 1024 px resolution, developed your site 1024px and set desired font site as a percent value. If a user has 1280px resolution, your site will be displayed at 1280px full window size or if a user use 800px resolution, your site will be displayed at 800 px full window size. If you change window size by draging from corners or change “Display Settings”, site will be displayed at full window without horizontal scroll bar.

It works at Chrome 2 too. My solution is for displayed any site at full window as explain above. Normally, when changed font-size with browser menu options, my solution reset it to suitable font-size for display at full window. But this is not working only Chrome 2 Beta and Lunascape 5 Beta. Everything is normal at other browsers.

Font size changes based on a window size via javascript is a huge no-no as far as I’m concerned. For one, it results in a jarring repositioning of text when the code resizes the font. More importantly, as people pointed out, it breaks usability. If you wish to give people control over font-size through your site (instead of browser controls) then just use the standard “increase/decrease font” buttons.

What’s more, this works against the idea of liquid (or fluid, or flexible, or what have you) layout. The way I see it, liquid layout is about using all the available space to show as much content as possible without scrolling, and while maintaining good, readable design. If you’re gonna increase font size with window you won’t be able to show more content.
